In this paper we present an efficient technique for sketch-based 3D modeling using automatically extracted image features. Creating a 3D model often requires a drawing of irregular shapes composed of curved lines as a starting point but it is difficult to hand-draw such lines without introducing awkward bumps and edges along the lines. We propose an automatic alignment of a user's hand-drawn sketch lines to the contour lines of an image, facilitating a considerable level of ease with which the user can carelessly continue sketching while the system intelligently snaps the sketch lines to a background image contour, no longer requiring the strenuous effort and stress of trying to make a perfect line during the modeling task. This interactive technique seamlessly combines the efficiency and perception of the human user with the accuracy of computational power, applied to the domain of 3D modeling where the utmost precision of on-screen drawing has been one of the hurdles of the task hitherto considered a job requiring a highly skilled and careful manipulation by the user. We provide several examples to demonstrate the accuracy and efficiency of the method with which complex shapes were achieved easily and quickly in the interactive outline drawing task.

Learning disorders are diagnosed when the individual's achievement on standardized tests in reading, mathematics, or written expression is substantially below that expected for age, schooling, and level of intelligence. Subtypes of learning disorders may be classified into two groups, language-based type learning disorders including reading and writing disorder, and nonverbal type learning disorder (NLD) such as those relating to mathematics & visuospatial skills, and those in the autism spectrum. Converging evidence indicates that reading disorder represents a disorder within the language system and more specifically within a particular subcomponent of that system, phonological processing. Recent advances in neuroimaging technology, particularly the development of fMRI, provide evidences of a neurobiological basis for reading disorder, specifically a disruption of two left hemisphere posterior brain systems, one parieto-temporal, the other occipito-temporal. The former is the reading system for beginner reading, the latter for skilled reading. Compensatory engagement of anterior systems around the inferior frontal gyrus(Broca's area) and a posterior(right occipito-temporal) system is noted in persistent poor readers in long-term follow up study. The theoretical model proposed to explain NLD's source is not right hemisphere damage, but rather the white matter model. The working hypothesis of the white matter model is that the underdevelopment of, damage to, or dysfunction of cerebral white matter(long myelinated fibers) is the source of this disorder. The role of an evidence-based effective intervention in the remediation of children with learning disorder is discussed.

The purpose of this study was to identify the relationship of one repetition maximum between flat bench press exercise and incline bench press exercise, and so 40 male students of U-university were sampled purposedly, who were skilled in flat bench press and incline bench press exercises. After measuring lRM of each exercise by free barbell weight, the correlation analysis and the simple regression analysis were examined by using SPSS 120 at a significance level .05. The conclusions were as follows; Firstly, it was identified that 1RM of flat bench press exercise and incline bench press exercise were $89.2{\pm}25.9kg$, $67.1{\pm}22.1kg$ respectively, and the coefficient of correlation between two variables was 0.969, so the relationship was positive correlation. Secondly, it was identified that the regression equation predicted 1RM of incline bench press exercise was significant actually and statistically, so it was expressed that the equation was -6.648 + 0.827 (1RM of flat bench press exercise).

Welding is one of the most fundamental and necessary work in the industry that demand sophistication of skilled workers. This study is to introduce welding simulator as a training tool, to verify its effectiveness and to measure satisfaction of the trainees. A group of freshman students at a Korea Polytechnics College in their twenties with less experience of welding participated in the study. They were divided into two groups and took a traditional training course (comparison group) and a training course with welding simulator applied reality/haptic technology (experimental group) for same hours respectively. To evaluate training effect, a national certificate test and a survey based on Phillips' ROI (Return on Investment) methodology were conducted by the students and the college respectively. And satisfaction survey among the students based on Kirkpatrick's Four-Level Evaluation Model was also carried out. The results showed that all students in the experimental group passed the national certificate test and the ROI of the experimental group for five years were 110% higher than the comparison group. Furthermore, 25% more students in the experimental group replied "very satisfied" about the overall training course and 75% more students in the same group found that the simulation was very similar to the real welding.

Our country's fur clothing industry has rapidly grown for a short time since it started with simple needlework of fur pieces, and now it is still developing as export industry that some enterprises besides general business firm export more than ten million dollars a year. However, it is true that fur clothing industry is still in unsatisfactory level in its size and system, compared with manufacturing or leather industry. Of course, we import crude material and processed fur on an entire base, and we have few wild fur on an entire base, and we have few wild fur animals because of our natural condition and it is hard to breed them. On the other hand, the world's fur industry shows that the demand of fur clothes is increasing as fur animal breeding is improved and developed and supply has become rather abundant with the help of fur clothing fashion since late 19th century : Also, there is a trend that some developed countries depend on importing rather than self-prodoction because of the character-istic of labor-concetntraled fur industry. Accordingly, considering this situation, we can expect fur clothing industry as promising export industry by analyzing the present situation of our country's fur clothing industry and suggesting its problems and solutions, and here are developing plans for growing fur clothing industry as promising export industry. First, smoothing delivery of crude material. Second, making high quality products and diversifying goods. Third, establishing effective competition system in fur clothing industry. Fourth, raising skilled man power. Lastly, there should be coopetation among the related fields in the aspect of policy including the support from the government.

The goal of the proposed Intelligent Assisting System - IAS is to assist human operators in an intelligent way, while leaving decision and goal planning instances for the human. To realize the IAS the very important issue of manipulation skill identification and analysis has to be solved, which then is stored in a Skill Data Base. Using this data base the IAS is able to perform complex manipulations on the motion control level and to assist the human operator flexibly. We propose a model for manipulation skill based on the dynamics of the grip transformation matrix, which describes the dynamic transformation between object space and finger joint space. Interaction with a virtual world simulator allows the calculation and feedback of appropriate forces through controlled actuators of the sensor glove with 10 degrees-of-freedom. To solve the sensor glove calibration problem, we learn the nonlinear calibration mapping by an artificial neural network(ANN). In this paper we also describe the experimental system setup of the skill acquisition and transfer system as a first approach to the IAS. Some simple manipulation examples and simulation results show the feasibility of the proposed manipulation skill model.

The large-sized, complex, and multi-storied construction industry caused the increasing construction amount together with insufficient skilled workers to increase the probability of occurring accident, resulting in the most construction accidents next to manufacturing industry. Death accidents have risen to serious level, compared construction industry with manufacturing industry along the numbers of workers. Due to the main feature of one-time industry receiving orders, open-air dispersed production activity and the long-complex production process, the continuous efforts to prevent and manage safety accidents were made but the results were of no effect. They didn't deeply analyze the falling accidents that consist of half death accidents in construction industry. This study has classified in detail Missteps, Slip, Trip, Unstability and the others on the basis of gait characteristics, occurrence types, frequency and intensity of death accidents. This study suggested the effective methods on the construction safety management according to the causes of falling accidents. This study will be expect to be used as the basic data in the procedure and the program of safety management.
